If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
Nitrification, as stated above, is formally a two-step process; in the first step ammonia is oxidized to nitrite, and in the second step nitrite is oxidized to nitrate. Different microbes are responsible for each step in the marine environment.
Nitrates and nitrites must be used with caution during curing. Both can be considered toxic and for that reason, strict limits on their use have been established. Usually, the amount of added sodium nitrite lies in the range of 50-200 mg/kg and nitrate in the range of 200 to 600 mg /kg.Excessive use of nitrate (too much) and/or nitrites can cause severe oxidation of the meat pigment producing a green pigment. This form of greening of cured meats is referred to as nitrite burn.This product was added to our catalog on Friday 28 July, 2006.xcessive use of nitrate (too much) and/or nitrites can cause severe oxidation of the meat pigment producing a green pigment.
